Which of the Top 5 Premier League's Big Money Transfer will make the biggest Impact?

Angel Di Maria [Real Madrid - Manchester United] £59.7m

Alexis Sanchez [Barcelona - Arsenal] £35m

Diego Costa [Atletico Madrid - Chelsea] £32m

Eliaquim Mangala [FC Porto - Manchester City] £32m

Cesc Fabregas [Barcelona - Chelsea] £30m

Cesc Fabregas for me, I think he's the signing that will propel Chelsea to the league. More important for them than even Costa.

For once, I can't argue with Crimey. The early signs are very promising for Fabregas & Chelsea. I'd love to be wrong though!!

Costa

Costa for me. Absolutely dominating at the top currently, and thats an extremely tough role to play at Chelsea. Shown himself to be a bull of a striker with wonderful feet.

Fabregas is a fantastic addition to Chelsea, and definitely gives them something different. However, of all those players, it's Costa who has the potential to make the biggest difference simply because he addresses the clearest weakness.

think di maria will make the biggest difference, cesc is a brilliant signing and costa will bang a fair few in with the support he has but chelsea already had a very good squad and massively under achieved last season. while we were awful and crying out for anybody who can play football, di maria will improve us more than either of the chelsea players will improve them

I think Costa, he could be the type of player that gives Chelsea the upper hand not only in the league but against the big continental powers. This Chelsea team in my mind is every bit as potent as the first edition Jose teams that dominated the league. To me Chelsea is now a top contender for the CL and the heavy favorite for the league. Last year their problem wasn't the midfield it was at striker and they went out and got probably the best guy that suited their team for that position. He is very drogba like. A mix of power, speed, technique and quite a big nasty streak as well.
